WATER-FILTER.

SPECIFICATION forming part of Letters Patent N o. 654,033, dated July 17', 1.900.

Application filed May 18,1900. Serial No. 17,083. (No model.)

To all whom it" may concer/t.-

Be it known that I, ELIJAH F. STEWART, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri,

5 have invented certain new and useful Improvements in Feed-Regulators for Water- Filters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of Io this specification. V

My invention relates to a water-filter, and has for its object to provide means in a device of the class named whereby the quantity of water passing to the filtering medium from 15 a supply-tank is automatically controlled to feed the water gradually and uniformly to the filtering medium, so that it is not forced rapidly therethrough in the filtering operation, but instead percolates slowly to accomzo plish proper filtration.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a vertical sectional View taken z5 through a filter equipped with my improvement. Fig. II is an enlarged sectional view through the regulator and the water-supply tank. Fig. III is a detail view of the perforated plate surmounting the filtering medium.

3o Fig. IV is a detail view of the perforated plate located immediately beneath the filtering medium. Fig. V is a detail view of the perforated disk by which the lower perforated plate is supported. Fig. VI is an en- 3 5 larged detail view of the grooved valve of the regulator.

1 designates the shell of the filter, open at its upper end and provided with a cover 2.v

The filtering material 3 is located water to be filtered is introduced, said supply-tank being suitably supported within the shell 1 at its upper end.

9 is a conveying-pipe` securedl to the tank 55 8, at the bottom thereof, and extending downwardly through the filtering material to the chamber 6 between the plate 4 and disk 5. Seated in the upper end .of the conveyingpipe 9 is a tubular valve-housing 10, pro- 6o vided with avalve-seat 11y and having apertures 12 in its wall, that provide communication from the tank 8 into the pipe 9. The valve-housing 10 is equipped with arms 13, by which it may be easily turned to connect 65 it to the pipe 9.

14. designates a float located in the tank 8 and having connected to it a stem 15, that carries a valve 16, located beneath the valvehousing 10 and adapted to be brought into 7o contact with the valve-seat 11 of said housing. The valve 16 is provided with grooves 17 at its edge, (see Figs. II and VI,) that provide passage-ways from the interior of the housing 10 into the conveying-pipe 9 when the valve 75 is seated against the housing, the purpose of which will hereinafter appear.

Surrounding the tank S is a clear-water chamber 18, that has communication through an aperture 19 in the wall of the shell into a 8o clear-water reservoir 20, provided with a lid 21. Beneath the disk 5 is a mud-chamber 22, into which enters a valved `pipe 23, through which the sediment deposited in the mudchamber may be extracted. 85

The float 14 is inclosed by a housing 24, provided with apertures 25, through which the water enters from the main portion of the tank to obtain access tothe valve-housing 10 and to surround the float. 9o

In the operation of the filter the water to be filtered is introduced into the tank 8 and passes through the apertures in the housing 24. to the conveying-pipe 9, into which it gains entrance through the apertures 12 `in the 95 valve-housing 10. The float 11i is normally held suspended in the water and supports the valve 16 against the seat 11 of the valvehousing 10. With the valve seated as stated it is necessary for the water passing from the roo tank 8 into the pipe 9 to flow only through the grooves 17 in said valve to pass into the amount of Water delivered to the body of filp tering material 3 is controlled according to the requirements of a slow and steady feed of the VWater to accomplish proper filtration. The waterpercolates slowly upwardly through the body of iltering material, seeking the level of the Water contained by the tank 8, and after passing through the filtering mate' rial enters the chamber 18 and flows therefrom into the clear-Water reservoir 2O in a filtered condition. The oat 14 remains elevated so long as there is sufficient Water in the tank 8 to support it. As soon as the su pply of Water has become diminished to a sufficient extent to allow the fioat to fall the valve 16 recedes from its seat, and each time that it does so the Water remaining in the tank S passes more rapidly into the pipe 9 and acts as a flush to remove any mud or sediment from thevalve 16 or the seat 1l.

I claim as my invention- 1. An automatic regulator for Water-filters comprising an apertured valve-housing, a oat, and a grooved valve carried `by said oat adapted to contact with said valve-hous ing, substantially as described.

2. In a device of the character described, the combination of a tank, a pipe leading therefrom, Aan apertured valve-housing seated in said pipe and provided with a valve-seat, a float located in said tank, and a grooved valve carried by said float adapted to contact with the valve=seat of said housing, substan-4 tially as described.

3. In a device of the character described, the combination of the shell containing a chamber at its upper end, a tank located in said ol1an1ber,a body of filtering material located beneath said chamber, a pipe leading from said tank through said filtering mateA rial, an apertured valve-housing located in the upper end of said pipe, and having a valveseat, a float arranged in said tank, and a grooved valve carried by said float adapted to contact with Vsaid valve-seat, substantially as described.
